Abstract

The effect of section of the rostral hepatic nerve (RNH), branch of the left abdominal vagus, on the circadian rhythm of tyrosine transaminase (TAT) activity in rat liver has been investigated. It has been shown that the midnight peak of TAT activity is suppressed after section of the rostral hepatic nerve and by subdiaphragmatic vagotomy, but is unaffected by sham-operation and section of the ventral abdominal vagus caudal to the emergence of the rostral hepatic nerve. It is concluded that the rhythm of TAT activity is under neural control, either directly or reflexely.

摘要

研究了左腹迷走神经分支——肝前神经（RNH）切断对大鼠肝脏酪氨酸转氨酶（TAT）活性昼夜节律的影响。结果表明，切断肝前神经和膈下迷走神经后，TAT活性的午夜峰值受到抑制，但假手术和在肝前神经出现部位尾侧切断腹侧迷走神经对此无影响。结论是，TAT活性的节律受神经控制，可能是直接控制，也可能是反射性控制。
